标题: ORA-27419: unable to determine valid execution [打印本页] 作者: admin 时间: 2016-9-2 11:08 标题: ORA-27419: unable to determine valid execution ORA-27419: unable to determine valid execution date from repeat interval Cause: The specified repeatinterval contained conflicting clauses that made it
impossible to ever find a matching date, e.g.,
'FREQ=YEARLY;BYMONTH=FEB;BYMONTHDAY=31'. Alternatively, the
scheduler reached its maximum number of attempts to try to find a valid
execution date. This occurs when theoretically there is a valid execution datefar in
the future, but the scheduler took too many attempts to determine this date. Action: Remove theconflicting clauses, or simplify the repeat interval so that it is
easier to determine the next execution date.
